WILLIAM HENRY MORGAN, OF ALLIANCE, OHIO.

APPARATUS FOR MAKING RAILROAD-TIES FROM STEEL RAILS.

To all whom it may concern:

Be it known that I, WVILLIAM H. MORGAN, of Alliance, in the county ofStark and State of Ohio, have invented certain new and usefulImprovements in Apparatus for Making Railroad-Ties from Steel Rails; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to an improvement in apparatus for making railroadties from steel rails, the object being to provide means forprogressively feeding a rail longitudinally to an expanding device,which operates to swage or forge the head of the rail laterally intowide flanges which latter constitute the base of the tie.

With this and other objects in View my invention consists in feeding ahot rail longitudinally under a swaging or forging die whereby the headof the rail will be swaged and expanded laterally on both sides of theweb.

My invention further consists in parts and combination of parts as willbe hereinafter described and pointed out in the claims.

In the accompanying drawings, Figure 1 is a, View partly in elevationand partly in section looking toward the front of the machine. Fig. 2 isa view in transverse vertical section of same. Fig. 3 is a view in rearelevation. Figs. 4 and 5 are views of the feeding mechanism. Fig. 6 is aview of a section of a rail with its head partly swaged or forged. Fig.7 is a view in section through the expanded portion of the partlyexpanded rail of Fig. 6. Fig. 8 is a plan view of Fig. 6. Figs. 9 and 10are views of a modified apparatus for swaging the rail and Figs. 11, 12and 13 are views of the upper die.

1 represents the frame or housing of the machine, and 2 and 3 the rolls,for feeding the rail in a step by step movement to the forging orswaging die. The roll 2 is journaled at one side in a bell crank lever 4mounted at its elbow in fixed bearing carried by the housing 1, and roll3 is likewise supported on bell crank lever 6 mounted on a fixed bearingcarried by the housing. The two bell crank levers 4 and 6 are pivotallyconnected to the ends of lever 7, which latter is mounted at its centerat 8 on the lever Specification of Letters Patent.

Patented Aug. 30, 1910.

Application filed January 13, 1910. Serial No. 537,961.

9 journaled at one end on fixed bearing 10, and connected at itsopposite end to the piston 11 of hydraulic cylinder 12. The oppositesides of the rolls 2 and 3 are similarly supported and connected to thepiston 11. I have however, in Fig. 4, shown the levers at one side ofthe feed rolls, the lever at the opposite side being simply aduplication of those shown. As the piston is forced inwardly the twosets of bell cranks 4 and 6 will be turned on their bearings thusforcing the feed wheel into contact with the rail section 14.

The upper roll 2 is positivelyactuated as will be hereinafter describedto feed the rail section 14 progressively, or step by step into orbetween the dies 15, secured to the die carriers 16 mounted to rock inthe housing 1, and each die carrier is provided with an inwardlyprojecting arm 17 as shown in Fig. 2, connected by a link 18, wherebythey are caused to rock in unison, and each is also provided with anupwardly and outwardly projecting horn 19, which is engaged by thecurved arm 20 on the togglelevers 21, for rocking the die holders andthe dies 15 carried by the holders. These holders are slotted to receivethe dies, and the two dies are shaped to receive the lower flange andweb of the rail 14 as, clearly shown in Fig. 2. Then the dies are closedonto the rail, they rest on the anvil 61, and are supported thereby,while the swaging or forging die 22 is in contact with the head of therail. The rail is pushed or drawn from a furnace into engagement withthe feed rolls 2 and 3, and is fed by the latter progressively or stepby step into and through the dies 15, and under and into a positionwhere the head of the hot rail will be acted upon by the reciprocatingupper forging or swaging die 22. This upper die is triangular in planand is provided at its front end with a downwardly beveled nose 22 andwith downwardly and inwardly beveled sides 22*. Its under side may beflat or unbroken throughout its area, but I prefer to cut it away at itscenter andrear as shown. Its lower face may also be horizontal orparallel with the lower dies, but I prefer to make it deeper at itsfront end or nose 22*, with gradual upper inclination toward the rearend, so as to produce a wide flange concaved as shown in Figs. 6, 7 and8. This die 22 is carried by toggle levers 21, and reciprocates betweenthe guides 23 formed integral with the housing 1. The toggle levers aresuspended from the top of the housing and are connected by pitmen 24with the crank shaft 25 of motor 26.

The die 22 is located with the point of its nose 22 in the verticalplane of the web of the rail being operated upon; it is reciprocatedvertically by the pitman 2st and toggle levers 21, and is guided in itsvertical movements, and held in its proper position relative to thelower dies, by the guides 23.

At each movement of the pitman 24:, the forging die 22 will be raisedand forced down into contact with the head of the hot rail. lVhenelevated, the lower edge of the nose 22 of the die 22 will be in a planebe low the top surface of the head of the rail, and in feeding the rail14, the distance the rail 14 moves at each feed, is preferably less thanthe distance between the upper end 22 and lower end 22 of the nose, sothat the top surface of the head of the rail will always be engaged bythe inclined edge 22*.

As the rail 1% approaches the die 22, the inclined nose 22 of thetriangular shaped die 22 engages the end thereof, and by its shapefurrows or cuts into and spreads the head laterally. Between thesuccessive strokes of the die 22 the rail is fed toward the latter, theamount of feed being, as pre viously stated, not greater than thedistance between the point 22 and the lower edge 22, so that the furrowmade by one stroke of the die will be elongatedby the next, and thelower edge of the nose always be within the vertical plane of the furrowor depression formed by the preceding blow of the die 22. The sides ofthe die 22 are also inclined as at 22 hence as the rail is fedforwardly, the metal constituting the head will be gradually swaged andlaterally expanded until it fills the forms in dies 15, and as the dieis thicker or deeper at its front or nose end, than at its rear end, theupper surface of the expanded fiange will be trough shaped as shown inFig. 7. This movement of the rail between the dies 15 and under die 22,is a progressive or step by step movement, the feed being first againstthe inclined nose 22" which makes the initial depression or cut in thehead of contact with the cam 37 by spring 38, and at each halfrevolution of the crank shaft 25, the cam 37 forces the arm 35 down andthe arm 33 up thus elevating the lever 31 so that with each upwardmovement of the arm 33 the pawls of the upper feed rolls will be movedto turn said wheel the proper feeding distance which may be regulated.The feeding movement of the rail occurs during the upward stroke of theupper die, and while the latter is out of contact with the rail.

The horns 19 of the die carriers 16, rest adjacent to the free ends ofthe arms 20, which as previously explained are carried by the togglelevers 21. As shown they are secured to the lower members of saidlevers, and may be integral with or secured to the same so as to move inunison therewith. As the toggle levers are moved to the opposite sidesof the vertical center, they depress one arm 20 and elevate the other.The arm depressed contacts with the horn immediately under same, thusturning its die carrier on its axis, and as the two die carriers areconnected, they are simultaneously turned in a direction to release therail, which remains free, until released by the movement of the togglelevers in 'the opposite direction. It is during this period, while therail is free from the dies, that the rail is fed forwardly.

lVith this apparatus I take old worn rails, heat them and by forging andexpanding the head laterally so as to form side flanges, I produce a tiewhich is structurally as strong as the rail from which it was made. Inuse the expanded head of the rail becomes the base of the tie, the baseof the rail forming the bearing surfaces for the rails.

l/Vi'th this apparatus the clamping dies and expanding die are short ascompared with the rail, and as the latter is fed endwise under theforging die, it will be seen that any length of rail may be reworkedthus producing ties of any length.

lVhile I have referred to the reworking of old rails to produce ties, itwill be evident that other shapes comprising a web and an enlarged headmay be used in lieu of rails, hence I would have it understood, that allreference to rails in the specification is intended to comprehend andinclude any shape or structure having a web and an enlarged portion atone edge thereof.

' In the construction shown in Figs. 9 and 10 I have connected theforging die to the piston of an hydraulic apparatus, and con nected thefeed rolls to the piston of the apparatus, by the mechanism shownwhereby they are operated in sequence. In this modification I havemounted the lower dies 15 on a heavy spring 15 seated at its ends inrecesses in the base of the apparatus, the spring having an upwardlyprojecting portion which rests between the dies 15 and prevents lateralmovement thereof.

\Vi'th this construction, when the upper die is out of contact with therail, the spring 15 elevates the two dies 15, and as the latter aremounted on inclined ways or supports, they separate and release therail. As the upper die 22 engages the rail it first depresses it and thedies 15 and spring 15 until the latter is firmly seated on the frame ofthe apparatus, after which it operates in the manner previouslydescribed. The details of this modification are not herein claimed butare specifically reserved for a subsequent application. Neither do Iclaim specifically the means for actuating the lower dies nor thefeeding device as they are shown and claimed in my application No.520,857 filed October 4th, 1909.

It is evident that many slight changes might be resorted to in therelative arrangement of parts shown and described without departing fromthe spirit and scope of my invention hence I would have it understoodthat I do not wish to confine myself to the exact construction andarrangement of parts shown and described, but,

Having fully described my invention what I claim as new and desire tosecure by Letters-Patent, is
